Project 8. <strong>Survey</strong>s for threatened<br />

pheasants in Borneo<br />

Aims: to conduct extensive distribution surveys of<br />

threatened pheasants in Borneo; to collate <strong>and</strong> assess<br />

existing <strong>and</strong> new information.<br />

Justification: knowledge of Indonesian pheasants remains<br />

poor. The country has the longest list of birds believed to<br />

be threatened with extinction. In many cases, however,<br />

this reflects problems presumed to have arisen as a result<br />

of habitat loss or degradation rather than direct evidence<br />

of declines in numbers. The threats facing Indonesia’s<br />

biodiversity are very real, but the continuing lack of<br />

baseline information on pheasants prevents any objective<br />

assessment through which to propose appropriate<br />

conservation actions. New information on the threatened<br />

species of pheasant known to occur on the isl<strong>and</strong> (Bornean<br />

peacock-pheasant, Bulwer’s pheasant, <strong>and</strong> crestless<br />

fireback) is needed, but there is an urgent requirement for<br />

all existing information to be collated <strong>and</strong> assessed.<br />

Project description: the isl<strong>and</strong> of Borneo covers 755,000km 2<br />

<strong>and</strong> comprises three countries. This means that establishing<br />

the distribution <strong>and</strong> status of all its Galliformes will not be<br />

easy, but there is much scope for surveys in many parts of<br />

the isl<strong>and</strong> at various times of year. The PSG will attempt<br />

to collate any site records for other species in Borneo, as<br />

well as any unexpected absences. These data will be sent to<br />

relevant SSC Specialist Groups. At a minimum,<br />

information on exact locality, altitude, date, <strong>and</strong> habitat<br />

type should be collected. All information on Galliformes<br />

species should be made available to the Asian Galliformes<br />

Sites Database (Project 3).<br />

Timescale: projects of any duration can contribute useful<br />

information.<br />

Resources: needs will vary depending on the length <strong>and</strong><br />

scope of individual surveys.<br />

Project 9. Taxonomic re-assessment of<br />

pheasants<br />

Aim: to develop a stable nomenclature <strong>and</strong> taxonomy for<br />

the pheasants.<br />

Justification: the species remains the most practical level<br />

at which to direct conservation action. Such action,<br />

therefore, relies on the correct identification of species <strong>and</strong><br />

the robust definition of species limits. However, recent<br />

advances in taxonomic thinking (e.g., species concepts,<br />

Evolutionarily Significant Units), <strong>and</strong> especially<br />

phylogenetic analyses based on DNA sequences, have<br />

thrown into some doubt the validity of certain pheasant<br />

Research is required on the<br />

Bulwer’s pheasant of Borneo<br />

to assess more accurately its<br />

conservation status.<br />
